Memory Bank Function

The E5AX-BA/E5EX-BA has 8 memory banks (memory bank 0
through 7) where parameters such as main setting, alarm values,
PID constants, and input shift values can be preset. By switching
from a memory bank to another, different parameters can be se­lected

at a time with ease.

Basically, the temperature range that can be measured is deter­mined

by the temperature sensor to be

used. For example, when a
K-type (chromel-alumel thermocouple) temperature sensor is se­lected, the measurable range is from –200° to 1,300°C. However,
this temperature range can be narrowed, for example, to 0° to
400°C.
